2982 (increase in sales) x .15 (assumed tip amount) = + $447 divided by all tipped employees. But you have to remember even many small chain restaurants have 15-25 tipped employees this nets to very little increase in income per tipped employee and zero increased income for non-tipped employees. Next, subtract from that small increase all the money they used to make from theft and overall they are likely coming out of the deal with less income.
